Tonight's episode of Pretty Little Liars was insanely boring, except for one teensy detail: Spencer's evil twin was (maybe) in it. I'm still freaking out, but let's take one step at a time. Here's what went down…

We open with Emily and Alison looking sad and furrowing their brows about their effed-up baby situation. (If you forget, A.D. implanted Emily's eggs into Alison's body. This show has no chill.) They're both pissed and rightfully feel violated; Emily suggests getting blood work done to confirm this is actually true…but is that necessary? We all know it is. (Spoiler alert: They end up getting that blood test, and, surprise, Emily is the mother!)

Emily and Hanna decide to raid Lucas' house for proof that he knew Charlotte. They end up finding a handmade comic book that he made with Charlotte, which makes him the prime suspect for A.D. But he's clearly not: I. Marlene King wouldn't reveal A.D.'s identity this early.

Meanwhile, Aria is lurking behind a dumpster, avoiding calls from A.D., who's trying to recruit her to the dark side. She winds up accepting a call from A.D., who has somehow disguised himself/herself as a virtual Aria. It's terrifying. A.D. says some empty threatening things. Aria is scared. I'm scared. Later, Aria tells A.D. about Hanna and Spencer's impromptu trip to find Mary Drake. She also tells A.D. about the comic book Hanna and Emily found that definitively connects Lucas to Charlotte. WTF! Why is Aria being a mole this episode?

Hot Cop clearly thinks the liars killed Archer Dunhill. Spencer tries to distract him with gross cupcakes, but he isn't budging. He sees right through their liiiies, and I'm very happy about it.

Nicole's parents want Ezra to visit her doctor again. He wants to go, and Aria is pissed about it. They have an emotional fight, and Ezra leaves despite Aria being viscerally upset. Dump. Him.

Emily finally makes her decision about the baby: She wants Alison to have it, which Ali isn't exactly thrilled about at first. They don't know who the father is, but Emily says knowing that it isn't Archer Dunhill is good enough for her (amen). Alison eventually agrees, but she's terrified. I don't blame her!

Spencer comes home and finds a note from Mary Drake inside a wine glass. Instead of picking up the phone and calling her, she puts another message in the wine glass like it's 1892. Mary Drake later responds by dropping a key in the wine glass. This will probably lead to something good, but I'm annoyed at the old-school communication.

Hanna goes back to Lucas' to retrieve the comic book, but it's missing. Surprise, surprise: A.D. convinced Aria to steal it because she's randomly on the dark side in this episode. She drops the comic book off at some locker at Rosewood High School, and A.D. gives her a black hoodie as a thank you. This storyline is pointless because Aria won't actually join the A.D. team. Stop giving this screen time!

Emily comes clean about the baby to Paige. She wants to stay with Paige while she's having Alison's baby, which is clearly the stupidest idea ever. Paige basically says, "Um, no. Alison sucks," and breaks up with Emily for the final time (hopefully). They have one more, admittedly sweet kiss. Don't let the door hit you on the way out, Paige. It's time to bring Maya back from the dead.

Minutes after dumping Emily, Paige breaks into Alison's house because she's deranged. She asks Alison if she's in love with Emily. Naturally, Alison avoids answering but eventually reveals that she loves how Emily makes her feel. "It's like she sees who you really are," she said. "Maybe that's the scariest part." Translation: She's in love with her. Emison is back on!

Mary Drake's note leads Spencer to a house. Hot Cop follows her there, which makes him significantly less hot, and questions her about Archer Dunhill's death. And he has receipts to back up his accusations—actual receipts from the night he and Spencer met. Spencer's shook.

"The reason I'm not afraid of it because you don't see a little Mona at that starting line." —Mona, on the board game

Mona tells Hanna that Lucas is trying to sell her fashion company from under her, which further confirms he's bad-news bears. Hanna then takes Mona home to show her the creepy game, and Mona's weirdly enticed by it (like, she takes photos of it and tries to cuddle with it). The board game then tries to stab Mona (because it's alive, damn it!), but she gets the upper hand by discovering its weakness: batteries. Mona tells Hanna she has to finish the game to wear out the batteries. She's probably right. (Remember, she was the first "A," so she's still low-key evil.) Hanna asks Mona to help her play the game. She refuses (because she's smart), but Hanna's stern monologue makes her come around. No!

"Batteries? I thought it operated on bitchiness." —Hanna, on the board game

Ezra weirdly bumps into Spencer and Wren at the airport. Spencer's wearing all black, and, at the end of their very strange conversation, she asks Ezra not to tell anyone he saw Wren with her. I might be jumping the gun, but was that…Spencer's twin? Their interaction was just too weird, and this is a popular theory. (FWIW, Twitter agrees with me.)

Ezra decides not to visit Nicole, after all. He comes home to Aria, and they share a tender moment. Spencer then gets another ominous wine-bottle note from Mary Drake, but who cares because SPENCER'S EVIL TWIN MIGHT'VE JUST MADE HER DEBUT. Bonkers.
